We have some old windows XP machines with graphics cards that don't support direct2d and therefor will be unable to get WebGL running. We need this to work temporarily until we can upgrade those machines to newer ones. Firefox however disables WebGL for these graphics cards so we cannot test if it will work or not (For good reason considering how unstable it could be on these cards.) Doing some research I've seen that people have enabled options in the Firefox about:config and got it working. Nothing so far has been successful. We've tried: - setting gfx.direct2dforce -enabled to true - setting layers.acceleration.force -enabled to true - Creating a batch file to trick Firefox into thinking we have a better graphics card. No matter what however we have gfx.blacklist.direct2d set to 3 which disables our WebGL. We cannot prevent that from popping up in the about:config. In about:support it continues to say "Direct2D has been blocked for your graphics driver version." Is there anything we can do to get our graphic cards working? We are using Intel(R) GMA 3150 cards.
